Research On Finished Product Warehouse Management Software Reengineering Of ERP Based On Bussiness Rules

Nowadays, Information technology has been in use in all areas of the life. The information technology developed so fast, while the related operation areas have also been developed rapidly, which result in the software crisis raged higher, when the software system can't be enhanced and evoluted, it will become a legacy system.Software reengineering aims at development of new systems by making use of legacy systems, while the method of business rules can easily solve the keep on changing problems in the business field. In the actual development process of the software, how to integrate the software reengineering with the business rules dynamicly to solve the adaptbility and the maintenability preferably will be the main study area of this essay.First, theories about software reengineering and operation regulation methods are introduced, the software reengineering is defined, general modeling and engineering strategy chioces, the definition of business rules, application charecteristics, assortment and the key technology of business rules management are summerised.Secondly, after analysing the dificiencies when the software reengineering theories are used in practice, and compare the relation between the system modification scale after introducing the rules engine with the cost for this modification, while the software reengineering is introuduced based on the business rules. With the finished products warehouse software reengineering of ERP as an example, combing the exampling modeling with the chareacter modeling, the application of business rules in the software reenineering are discussed in details.Finally, the business rules of the finished products warehouse management of ERP is distilled, and it is discribed in domain specific language, the architectonic for business rules control block is put-forward, the compiling using Drools tools for the business rules is initially reached.
